A list of topics we covered in the week of February 10 to February 16 of 2025
A vulnerability exists in the ABB Cylon FLXeon controller that allows unauthenticated access to the Building Management System (BMS) or Building Automation System (BAS) dashboard. This exposes sensitive information, including system status, events, and alarms related to HVAC operations. Additionally, an attacker could manipulate environmental controls such as temperature settings, potentially disrupting building climate regulation and operational safety.
A vulnerability exists due to an insecure backup.tgz file that, when obtained, contains sensitive system files, including main.db, SSL/TLS certificates and keys, the system shadow file with hashed passwords, and the license key. Although authentication is required to access the backup, an attacker with access could extract these files to retrieve stored credentials, decrypt secure communications, and escalate privileges by cracking password hashes. This exposure poses a significant security risk, potentially leading to unauthorized access, data breaches, and full system compromise.
A timing attack vulnerability exists in ABB Cylon FLXeon's authentication process due to improper comparison of password hashes in login.js and uukl.js. Specifically, the verifyPassword() function in login.js and the verify() function in uukl.js both calculate the password hash and compare it to the stored hash. In these implementations, small differences in response times are introduced based on how much of the password or the username matches the stored hash, making the system vulnerable to timing-based analysis.
In mid-March 2024, KrebsOnSecurity revealed that the founder of the personal data removal service Onerep also founded dozens of people-search companies. Shortly after that investigation was published, Mozilla said it would stop bundling Onerep with the Firefox browser and wind down its partnership. But nearly a year later, Mozilla is still promoting it to Firefox users.
Hazel discusses Interpol’s push to rename pig butchering scams as ‘romance baiting’. Plus, catch up on the latest vulnerability research from Talos, and why a recent discovery is a “rare industry win”.
A widespread phishing campaign has been observed leveraging bogus PDF documents hosted on the Webflow content delivery network (CDN) with an aim to steal credit card information and commit financial fraud. "The attacker targets victims searching for documents on search engines, resulting in access to malicious PDF that contains a CAPTCHA image embedded with a phishing link, leading them to
User sessions on ABB Cylon FLXeon controllers remain active for up to seven days, even after a client-side logout. Clicking "Log Out" does not properly revoke the session on the server, allowing attackers with access to stolen session tokens to maintain unauthorized access. This increases the risk of session hijacking and privilege abuse.
The ABB Cylon FLXeon BACnet controller uses a weak set of default administrative credentials that can be guessed in remote password attacks and gain full control of the system.
The ABB Cylon FLXeon BACnet controller suffers from insecure CORS configuration. Allowing all origins (app.options('*', cors()); can expose the API to data leaks, resource abuse, and potential XSS attacks.
